' To all whom it may concern:

Be it known that I, JOHN HENRY Browse, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new I and useful Improvements in J awed Tools, of which the following is a specification.

My invention relates to improvements in jawed tools, such forexample as pliers,pincers, tongs, and the like. The invention relates more particularly to what may be termed auxiliary jaw attachments for the jaws of such tools.

The primary object of the invention is the provision of an auxiliary rocking or pivoted jaw which may be readily and quickly attached to or detached from the jaw of an or dinary jawed tool for more effectively holding or grasping an irregular or headed article such as a spike, bolt, or the like.

A further object is the provision of a rocking or pivoted auxiliary jaw attachment which will readily conform to the contour or plane ol the article being grasped between it and the opposing main jaw.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part olthis specification Figure 1, is a side elevation of a jawed tool of the adjustable-jaw plier type equipped with the improved auX- iliary jaw attachment, the dotted lines showing the action or position of the same in connection with a headed or irregular shaped article such as a bolt, or the like.

Fig. 2, a similar view of the same with the In the accompanying drawings I have shown the improved auxiliary jawapplied to a jawed tool of the adjustable-jaw plier type comprising, in the present instance, the usual pivoted mem'bersoonsisting of handle members 1, pivotally connected by means of a pivot bolt or member 2, and terminating in 1 attached to one of the jaws l in any suitable and convenient manner, as for example,-by means of a pivot pin 4, as shown in Figs. 1, to 3, inclusive, of the drawings, or may be attached by means of a sleeve shaped jaw 3, provided with an integral pivot member i adapted to be slipped over one of the jaws of the tool and form a rocking or pivot point as shown in Figs. 5, and 6, of the drawings.

its a means oil adapting the face of the auxiliary jaw 3, to the form or contour of the article to be held between the auxiliary jaw 3, and the opposing or main jaw of the tool, the taco of the auxiliary jaw preferably extends or projects within the plane of the jaw to which it is attached, and is provided with a longitudinally extending bolt or article receiving recess 3 and a transversely extending article head receiving recess 3 Tu the terms shown in Figs. 1, to ll, inclusive of the drawings the pivot pin 4-, may 6X- tend through suitable openings in the sides oi the jaw clip.

In the form of auxiliary jaw shown in Figs. 5, and 5, ol the drawings, this form may be readily attached to or detached from any ordinary jaw without the necesslty of providing a hole in the jaw for receiving the form of pivot 4, shown in Figs. 1, to 3, in-

clusive, of the drawings, and it will be apparent that'in either instance the auxiliary jaw willrock upon its pivot to conform to the "form and plane of the article being grasped and this independently of the particular position or angle of the opposing jaw of the tool.

From the foregoing description, taken in connection with the accompanying draw- Having thus described some of the enibodiments of my invention, what I claim and desire to secure by Letters Patent, is,

1. In a jawed tool, a pivoted auxiliary jaw clip formed of a single blank of sheet metal and comprising side members detachably 7 mounted on opposite sides of one jaw of the a transverse cut out portion forming longitu'dinally and transversely extending article and head receiving recesses, respectively.

2. An attachment for a jawed tool, comprising an auxiliary jaw consisting of a single blank of sheet metal having side members adapted to embrace the opposite sides of'one of the jaws of the tool and provided witha face projecting beyond the plane of the face of the tool jaw and having a longitudinal depression for receiving work and a portion of said face being cut out forming a transverse recess, also adapted to receive the work.

In testimony whereof I have aflixed my signature in the presence of two witnesses.

JOHN HENRY RIDINGS.
